There are an endless number of pressure washer cleaning projects around the home, but let’s focus on the top 5 tough cleaning jobs, some of which would take hours to perform manually with the bucket-and-brush method. Although each of these pressure washer cleaning projects can be performed without the use of detergent, add in a job specific cleaning solution and things will move even faster than with just high pressure water alone.

Safety and Preparation

Before pressure washing we recommend preparing the work area. And always make sure to follow the manufacturer’s operating and safety instructions.

  • Always wear protective eyewear when operating a pressure washer.
  • Cover nearby plants and light fixtures.
  • Make sure nearby windows and doors are closed.
  • Sweep or brush away loose debris from the surface to be cleaned.
  • Before cleaning any surface with a pressure washer, an inconspicuous area should be cleaned to test for the optimal spray pattern and distance for best cleaning results.
  • If pressure washing a painted surface, make sure that any visible damage is repaired before using the pressure washer. If painted surfaces are peeling, chipped, or rusted, the pressure washer may lift the loose paint and exacerbate the peeling or chipping.
  • A pressure washer will clean most effectively when the water spray is angled at about 45° to the surface to be cleaned.
